JFET operation can be compared to that of a garden hose. A pn-junction is formed on one or both sides of the ffet, or surrounding it, using a region with doping opposite to that of the channel, and biased using an ohmic gate contact G.

Why an input characteristic of FET is not drawn? In the saturation regionthe JFET drain current is most significantly affected by the gate—source voltage and barely affected by the drain—source voltage. As with an ordinary diodethe arrow points from P to N, the direction of conventional current when forward-biased. This bfw1 was last edited on 26 Decemberat Why wedge shaped depletion region is formed in FET under reverse bias gate condition?

The current also depends on the electric field between source and drain analogous to the difference in pressure on either end of the hose.
The circuit diagram for vfw10 drain and transfer characteristics is shown in the figure1. Properly identify the Source, Drain and Gate terminals of the transistor.
Common emitter Common collector Common base. The depletion layer is so-called because it is depleted of mobile carriers and so is electrically non-conducting for practical purposes. It is given by the ratio of small change in drain to source voltage V DS to the corresponding change in gate to source voltage V GS for bfw01 constant drain current I D. The JFET shares this constant-current characteristic with junction transistors and with thermionic tube valve tetrodes and pentodes. Pinch-off occurs at a particular reverse bias V GS of the gate-source junction.
In general, the larger the transconductance figure for a device, the tet the gain amplification it bf1w0 capable of delivering, when all other factors are held constant. Ohmic contacts at each end form the source S and the drain D.

This may lead to damage of FET. While performing the experiment do not exceed the ratings of the FET. A JFET has a large input impedance sometimes on the order of 10 10 ohmswhich means that it has a negligible effect on external components or circuits connected to its gate.

It exhibits no offset voltage at zero drain current and hence makes an excellent signal chopper. Thus, JFETs are sometimes referred to as depletion-mode devices. The fragile insulating layer of the MOSFET between the gate and channel makes it vulnerable to electrostatic damage during handling.
It typically has better thermal stability than a bipolar junction transistor BJT 3. Conversely, to switch off a p -channel device requires p ositive V GS.
